Code Behind variable is not accessible from .aspx page

I have a variable in an aspx.cs page called VersionNumber:

namespace App_name
{
  public partial class Default : System.Web.UI.Page
  {
    public string VersionNumber = System.Reflection.Assembly.GetExecutingAssembly().GetName().Version.ToString();
    protected void Page_Load(object sender, EventArgs e)
    {

    }
  }
}

This variable should be accessible in the .aspx page like such, but instead there is a red squiggly line telling me it doesn't exist in this context:

<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Default.aspx.cs" Inherits="App_name.Default" %>

<!DOCTYPE html>

<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title>App Name <%=VersionNumber %></title>
<script type="text/javascript" src="scripts/jquery-1.12.4.js"></script>
<script type="text/javascript" src="bs/js//bootstrap-typehead.js?<%=VersionNumber %>"></script>
<script type="text/javascript" src="scripts/Default.js?<%=VersionNumber %>"></script>
<script type="text/javascript" src="scripts/Helper.js?<%=VersionNumber %>"></script>

etc.

How can I make VersionNumber accessible in the .aspx page? thanks

the solution to my problem was to write the namespace as well as the class name in the Inherit part of the aspx page, like such: 

Inherits="Solution_History.Default"

I have tested your code and come to the following solutions:

The cs file should be like this without a change to the aspx page:

namespace Solution_History
{
    public partial class Default : System.Web.UI.Page
    {
        public string VersionNumber = System.Reflection.Assembly.GetExecutingAssembly().GetName().Version.ToString();
        protected void Page_Load(object sender, EventArgs e)
        {

        }
    }
}

Not adding the namespace to the cs file then the first line in the aspx should be:

<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Default.aspx.cs" Inherits="Default" %

I've tried both possibilities and both showed version numbers.

Hope this helps.
